excuting unix program.

[Former Member]

Hi.

I just want excute java.exe in bw unix without using function 'SXPG_CALL_SYSTEM'.

cause that function has limit number of command string.

I think I can use this command but somehow it returns null.

don't know what is problem and actually not sure usage of CALL 'SYSTEM' function.

anyone can fix this problem?

DATA: INFO_SGL(700) TYPE C OCCURS 0 WITH HEADER LINE.

data: COMMAND_STR type string.

data: CODE_number_500 type string.

CODE_number_500 = '43423424324........'.

concatenate '/opt/java1.3/bin/java -jar'

' test_v2.jar'

CODE_number_500

INTO COMMAND_STR.

CALL 'SYSTEM' ID 'COMMAND' FIELD COMMAND_STR ID 'TAB' FIELD INFO_SGL-SYS.

loop at info_sgl.

return_value = info_sgl.

endloop.

thank you.

Hi,

Try using trx SM69 to register the UNIX command and then use it.

I think system functions are not for external use.

hi.

thank you for answer.

but that is useage of function 'SXPG_CALL_SYSTEM'.

I already done this but 'SXPG_CALL_SYSTEM' can work because parameter 'CODE_number_500' is too long.

so I try find other way that is send string directly.

and some other programs use that 'SYSTEM' function.

so think that can be work for external use.

but don't know how to get useage of this function.

Hi,

Length of the parameter COMMANDNAME is 18.

Hence 'CODE_number_500' should work.

There must be some other problem.

Go thru following documentation.

Hope it helps.

FU SXPG_CALL_SYSTEM

Execute an External Command

Functionality

SXPG_CALL_SYSTEM: Execute External Command (Express Method)

Using this function module, you can:

o Check a user's authorization to execute a command

o Execute the command

To determine the system on which the command should be executed, the

function module uses by default the current host system and the current

operating system type of the user.

As the function module is RFC-capable, you can use the RFC interface

(Remote Function Call Interface) to run the function module in a

different SAP application server. The external command is then

accordingly executed in the host system of the other SAP server.

SXPG_CALL_SYSTEM uses the following rules to determine which variant of

a command is used for the execution:

o If a command with the same operating system type as the one in the

sytem field SY-OPSYS exists, this definition is used for the

execution of the command.

o If the first check fails, the syntax group for SY-OPSYS is

determined. A syntax group is an SAP construct that groups operating

systems that use the same syntax for commands and filenames. If a

command whose operating system type matches the determined syntax

group, this definition of the command is used.

o If no matching definition is found for the syntax group, the

function module searches for a definition with the operating system

type ANYOS (executable in all supported operating systems). This

definition is then used, if found.

o Otherwise, the exception COMMAND_NOT_FOUND is triggered.

Use

there is misunderstanding .

value of 'CODE_number_500' is not just '43423424324'.

that is huge number of series about 500 character.

I already used that 'SXPG_CALL_SYSTEM' function before and works well until that parameter is less than 255 long.

after exceed 255 character that function are not working anymore so I need get other solution that is my problem.

thanks for finding these reference.

do you have any idea executing external unix program other than this?

[Former Member]

Hi,

Not very sure but did you try using the parameter

ADDITIONAL_PARAMETERS

for the function module 'SXPG_CALL_SYSTEM' ?

It helps in specifying the arguments to be passed to the ext command.
